5 lut 2024 · Mach 2 is a velocity equivalent to twice the speed of sound, which varies depending on factors such as altitude, temperature, and air density. At sea level, the speed of sound is approximately 767 miles per hour (1,235 kilometers per hour). Therefore, Mach 2 translates to roughly 1,534 miles per hour (2,470 kilometers per hour).
One meter per second is exactly 3.6 kilometers per hour, or about 2.237 miles per hour. How fast is Mach 2? What is Mach 2 in meters per second? This simple calculator will allow you to easily convert Mach 2 to m/s.
Mach 2 represents twice the speed of sound. The speed of sound, or Mach 1, is approximately 343 m / s 343\mathrm{~m/s} 343 m/s in air at sea level under standard conditions. So, at Mach 2, an object is traveling at: 2 × 343 m / s = 686 m / s 2 \times 343\mathrm{~m/s} = 686\mathrm{~m/s} 2 × 343 m/s = 686 m/s
Mach Speed is when an object moves faster than the speed of sound. For normal and dry conditions and temperature of 68 degrees F, this is 768 mph, 343 m/s, 1,125 ft/s, 667 knots, or 1,235 km/h. If you’ve ever watched a movie with fighter jets in it, chances are you’ve heard them talk about Mach numbers.
The speed of sound is roughly 295 m/s (660 mph) at the altitude at which commercial jet aircraft normally fly. The now decommissioned British Airways and Air France supersonic Concorde cruised at 600 m/s (1,340 mph). Simple division shows that this speed is roughly twice the speed of sound or Mach 2.0, which is exceptionally fast.
Convert Mach number (M) to another unit of speed such as knots, speed of sound, or speed of light, and see the conversion formulas.
The Mach number (M or Ma), often only Mach, (/ m ɑː k /; German:) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. [ 1 ] [ 2 ] It is named after the Austrian physicist and philosopher Ernst Mach .
